The TPS74901EVM-210 facilitates evaluation of the TPS74901 low-dropout linear regulator IC.

These regulators require a low-power bias voltage, VBIAS, and a power input voltage, VIN. The regulator is capable of providing output voltages down to 0.8 V, output currents up to 3 A and has an integrated supervisory circuit with open-drain output that goes to high impedance when the output voltage reaches regulation (power good or PG).

  • Soft-Start pin provides a linear startup with ramp time set by external capacitor
  • 2% accuracy over line, load and temperature
  • Supports input voltages as low as 0.9 V with external bias supply
  • Adjustable output (0.8 V to 3.6 V)
  • Ultra-low dropout: 120 mV at 3.0 A (typical)
  • Stable with any output capacitor ≥2.2 µF
  • Excellent transient response
  • Open-drain power-good
  • Active high enable
